Who We Are
Phantom Security Ltd is a specialist cyber security consultancy delivering rigorous, senior-led assessments for modern businesses. Our expertise spans traditional web applications and infrastructure, extending into blockchain and Web3 protocols, so clients get one team capable of securing everything they run. From single applications to complex, multi-service environments, we bring the same disciplined approach to every engagement.
Every engagement is led by senior practitioners with deep, hands-on offensive security experience. We combine rigorous methodology with real-world attacker tradecraft to deliver findings that are accurate, actionable, and grounded in genuine expertise, not automated output. Reports are written to be used, not filed away: clear severity ratings, reproducible steps, and remediation guidance your engineering team can act on immediately.
Our Approach
Evidence-Based Testing
We validate every finding before it reaches your report, so what you get is signal, not scanner noise.
Rigorous Methodology
Every engagement follows the same structured, repeatable process, from scoping through retest.
Long-Term Partnership
We work with clients across multiple engagements, not just point-in-time assessments.
